Lenovo Yoga Pro 7 14ASP9 fails to wake up from suspend mode

Brief summary of the problem:

System fails to wake up from suspend mode on Lenovo Yoga Pro 7 14ASP9. When the system enters suspend mode, the power button indicator continues flashing, but the system remains completely unresponsive to wake attempts via keyboard or power button. This issue occurs consistently and is easily reproducible with kernel version 6.11.5. The system works correctly with nomodeset, suggesting it's an AMDGPU-related issue.

    drm/amd/display: fix s2idle entry for DCN3.5+
    
        To be able to get to the lowest power state when suspending systems with
    DCN3.5+, we must be in IPS before the display hardware is put into
    D3cold. So, to ensure that the system always reaches the lowest power
    state while suspending, force systems that support IPS to enter idle
    optimizations before entering D3cold.
